Trunk Reservoir Cooling Modification
Hi,
Anyone in the South Florida area familiar with how to do the trunk reservoir intercooler cooling modification. I am off work this week and I really want to get this mod done before I take my 65 to RENNtech for an ECU upgrade. Any help would be appreciated. Thanks.

France2112, Since you are going to Renntech for "tuning", ask Harmut for his
"upgraded" intercooler electric circulating pump kit that comes with additional
cooling [auxiliary radiator] capacity. Please don't mess with trunk mounted
clap-trap. You will have terrible reliability problems. The Renntech system is
simple and well integrated, which keeps with the elegance of German engineering.

But if you want to go to Renntech and cough the extra 3K go right ahead.

. I don't want to wait that long but it may be worth it for a custom tank. Where did you get yours?Thanks again to both you and Sean

Got it. I forwarded the link to my tech. I will call him tomorrow and set it up. What tank did you use? There is a guy named Donny that makes custom tanks. He is a welder. I may have him make me a round one that will fit exactly where the spare tire is but it will take 2 weeks. I don't want to wait that long but it may be worth it for a custom tank. Where did you get yours?
Thanks again to both you and Sean.

Let's see: the $expensive Renntech system adds a total (fluid included) of 20 lbs to the
front of the car and works as represented. The trunk mounted system is now reported
reliable [that is good news] and weighs how much? The 5 gallon tank full of fluid in
itself is 50 lbs plus all the plumbing to and fro the front of the car (with the fluid in it,
I approximate another 1 1/2 gallon= 15 lbs). I believe performance in a car is about
removing mass not the other way around. As to expenses, are these V12 MBs not already above the paycheck of many people? How much are you spending when
you go on a racing outing? I think the $argument should be remanded to
price vs efficiency (specific fuel consumption, anyone?) and reliability vs performance
(stopwatch).
This being said, I love our V12s (I have two) and our collective passion!

^^I see your point. But in my eyes it was more beneficial to ME, and the gains I was expecting were substantial, I wanted the capability of putting Ice at the track, plain and simple. I saw a gain of nearly 30rwhp with a reservoir full of ice. In terms of the 50 lbs, it did not mean much when my car was laying down 900+rwtq.

I fully understand and appreciate the trunk reservoir mod from a hard racing viewpoint;
the results with ice are indeed spectacular. I use my car on long distance cruises at
"elevated" speeds where the Renntech system keeps-up nicely. Under harder
circumstances or sustained 100F OAT along the whole 1000 miles route, I would
definitively install a much larger IC auxiliary radiator.
Have fun guys!

You guys are forgetting a very important bit of info on this Reservoir trunk mod (at least on the SL600) it comes w/a full spare wheel/tire tools/air-inflator machine etc weighed close to 100lbs
It's ALL removed w/this mod, the new Tank & ALL plumbing + extra CM30 pump weigh 15lbs @ best then full figure 6 gallon's 8.34 lbs per gallon = 50.04 LBS so in total (@ least in my exp w/SL600) that's 65 Lbs, I still lost 35 odd lbs overall + gained 30 rwhp. Win-Win situation period

It should be known the SGC (Steve) has a 2006 CL65 with a RENNtech ECU/TCU, carbon fiber airbox, and intercooler upgrades that will wipe almost any exotic car on the road. He consistently runs 10's in the 1/4 mile and ran a full mile hitting a top speed of 187 MPH. This beat virtually every car at the meet including tuned Corvette ZR1's. So I guess his car is proof that although the trunk mounted reservoir does make sense and good consistent gains, it appears to not outperform the front mounted heat exchanger and stronger pump
. For me, the trunk reservoir is nicer because of the price!!! It comes down to price most of the time unfortunately. I want my cake and eat it too I guess. I don't want to spend 3K+ for the RENNtech intercooler upgrade but the trunk reservoir is a bit hackish. It is not a manicured upgrade like the RENNtech one. Decisions decision

Good point. Did you ever data log your IAT before and after the RENNtech intercooler upgrade? I go to the track only on occasion and I actually want a modification that will be consistant for "long distance cruises at "elevated" speeds." If you tell me that you notice a difference before and after the instal then for me it may be the way to go. Appreciate your opinion.

Keep in mind that the increased amount of coolant contained in the tank needs to have sufficient cooling. Increased coolant capacity requires a larger heat exchanger. I can tell you that your IAT's will be HIGHER in traffic with a 5 gallon tank and stock heat exchanger.
